Summary
Wide or radical surgical procedures for giant-cell tumors of bone offer zero local recurrence, significantly outperforming intralesional and marginal excisions. Early recurrence is common within three years post-surgery.
Area of Science:
- Orthopedics
- Surgical Oncology
- Bone Tumors
Background:
- Giant-cell tumor of bone (GCTB) is a primary bone tumor typically occurring in skeletally mature individuals.
- GCTBs are often found in the epiphysis and metaphysis of long bones, with potential for local aggressiveness.
Purpose of the Study:
- To analyze the long-term outcomes of surgical treatment for giant-cell tumors of bone.
- To evaluate the correlation between surgical technique, radiographic grade, and local recurrence rates.
Main Methods:
- Retrospective review of 327 patients with giant-cell tumor of bone treated at Istituto Rizzoli.
- Analysis of 280 patients with adequate follow-up (2-44 years) and 331 surgical procedures.
- Radiographic grading (Grade I, II, III) and classification of surgical approaches (intralesional, marginal excision, wide/radical excision).
Main Results:
- Local recurrence rates were 27% for intralesional procedures, 8% for marginal excisions, and 0% for wide/radical procedures.
- Recurrence rates did not correlate with radiographic tumor grade.
- 90% of local recurrences appeared within three years after surgery.
Conclusions:
- Wide or radical surgical excision is the most effective treatment for preventing local recurrence of giant-cell tumors of bone.
- Intralesional and marginal excision techniques are associated with significant rates of local recurrence.
- Close follow-up is crucial in the first three years post-surgery to detect early recurrences.
